DS320PR1601ZDGR

Signal Buffers, Repeaters, Splitters Overview

The DS320PR1601ZDGR is a 32-channel (16-lane in each direction) linear redriver designed for PCIe 5.0, CXL 2.0, CCIX, and UPI 2.0 interfaces up to 32 Gbps. It features an ultra-low latency of 130 ps and low additive random jitter of 50 fs for PRBS data. The device operates on a single 3.3 V supply with a low active power consumption of 164 mW per channel. It includes 64 integrated AC coupling capacitors on Tx pins inside the package to save board space. The CTLE provides boosts of 21 dB at 16 GHz. It supports x4, x8, and x16 bus widths and utilizes an I2C/SMBus or EEPROM programming interface.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the component against the official Texas Instruments datasheet SNLS683 to confirm specifications. Ensure the ZDG package variant matches the required 354-pin BGA footprint. Check for moisture sensitivity levels and recommended operating conditions before integration into the design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring transparent linear redrivers for PCIe 5.0 or CXL 2.0 links. Consider its compatibility with Intel retimer common footprints if board space optimization is critical. Evaluate the 164 mW/channel power consumption against thermal constraints in dense server environments.
